This article mainly explains "how to use golang to achieve cpu memory performance monitoring and tuning", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "how to use golang to achieve cpu memory performance monitoring and tuning" bar!

Directly say that the first installation of graphviz that can generate cpu performance

Golang will use it to generate cpu performance diagrams and configure the bin directory in the root directory after installation into the environment variable

Enable the performance monitoring code in the code as follows: package mainimport ("flag"gamelogic/logicFrame"net/http" _ "net/http/pprof") func main () {defer func () {if err: = recover () Err! = nil {}} () config_path: = flag.String ("Config", "config.cfg", "config file path!") Flag.Parse () go func () {http.ListenAndServe ("0.0.0.0 nil)} () gamelogic: = logicFrame.NewGameLogicServer (* config_path) gamelogic.Start ()}

Because the framework here may be websocket protocol over http or tcp or udp protocol, another http protocol is directly opened here for performance monitoring.

Open the cmd command to generate a cpu performance diagram

Go tool pprof http://192.168.124.18:6060/debug/pprof/profile # takes about 30 seconds to generate the data used by cpu and then enters the interactive command

(pprof) web # directly enter web to view the usage diagram of cpu performance

Thank you for reading, the above is the content of "how to use golang to achieve cpu memory performance monitoring and tuning". After the study of this article, I believe you have a deeper understanding of how to use golang to achieve cpu memory performance monitoring and tuning, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
